// RUN — FITS

Can the AMD Instinct MI455X run ERNIE-4.5-VL-424B-A47B (文心大模型4.5)?

Yes — here's how fast and up to what context, with real measured numbers.

Q4 yes 302k 52-63.6 t/s ~0.1-0.1 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.

FAQ

Can the AMD Instinct MI455X run ERNIE-4.5-VL-424B-A47B (文心大模型4.5)?

Yes. At Q4 it generates ~52-63.6 tok/s and fits up to 302k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.1-0.1 tok/s.

How much context fits?

At Q4, up to about 302k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
